我有一个弹出视图显示给用户显示一些信息,目前视图的框架是黑色,半透明框。我想对此框应用一些模糊,以提高呈现给用户的内容的清晰度。
我有这段代码:
class PinDetails : UIView {
var popupView:UIView!
var txtName:UITextField!
var img1:UIButton!
var img2:UIButton!
var img3:UIButton!
var selectedIndex:Int!
var dictLocation:[String:String]!
var blur:UIBlurEffect = UIBlurEffect(style: UIBlurEffectStyle.Light)
override init(frame: CGRect) {
super.init(frame: frame)
var effectView:UIVisualEffectView = UIVisualEffectView (effect: blur)
effectView.frame = frame
addSubview(effectView)
popupView = UIView(frame:TCRectMake(x: 25,y: 120,width: 270,height: 285))
popupView.layer.cornerRadius = 20
popupView.backgroundColor = UIColor(white:0, alpha: 0.5)
self.addSubview(popupView)
我试图实现的模糊代码似乎不起作用,xcode声明:
instance member 'blur' cannot be used on type 'PinDetails
。
任何帮助表示感谢,我对Swift相当新鲜:)
答案 0 :(得分:2)
尝试放置
var effectView:UIVisualEffectView = UIVisualEffectView (effect: blur)
effectView.frame = frame
addSubview(effectView)
内部init()。您正在使用尚未初始化的属性。

我建议您使用您创建的Popupview框架来创建visualeffectview。在init()
中试试这个 // Create the popup view
popupView = UIView(frame:CGRectMake(25,120,270,285))
popupView.layer.cornerRadius = 20
popupView.backgroundColor = UIColor(white:0, alpha: 0.5)
// Create the Effect View and apply to Popup view
let effect = UIVisualEffectView(frame: CGRectMake(0,0,popupView.layer.frame.width, popupView.layer.frame.height))
effect.effect = blur
popupView.addSubview(effect)
// Add the popupview to the main view
self.addSubview(popupView)
